KIM, Woon Soo* & CHOI, Yae Chin**(University of Ill., U.S.A.* & Chunchon Agricultural Coll.**) Studies on the viruses of radish mosaic. Kor. Jour. Bot. VI (2):9-21, 1963. A mosaic diseased radish collected from the suburb of Seoul, in November, 1961 was used for studing the host range, physical properties, purification, insect transmission, and electron microscopy. A Japanese strain of raddish mosraic (RPV) was also used with Korean strain of radish mosaic (KRMV) for a comparative study. The two viruses, KRMA and RPV, were identified by the difference in host range, insect transmission and electron microscopy. The KRMA was severely infective on tobacco and Nicotiana glutinosa, while on Gomphrena globosa was immune to the virus. RPV produces necrotic local lesions on Comphrena globosa but did not infect tobacco and N. glutinosa. Among varieties of radish, Seoul, Akamaroo, Akanagea, Koong-Joong showed more severe symptoms than Simoo, Minong, Paek-soo, which appeared to be fainly resistant. In a number of tests, it was found that the virus KRMA retained its infectivity until to a dilution of 1:2,000, heating at 58˚C for 10 minutes, and aging in vitro for 7 days at room temperature. The RPV was not inactivated until it was diluted to 1:2,000, heated to 56。C, and aged for 6days. The KRMV was readily transmitted by the aphid (Myzus persicae Sulz). The virus RPV was not transmitted by the aphid in a number of tests. Partialy purified viruses using ammonium acetate buffer, salting-out by ammonium sulfate and centrifugation of high and low speed were highly infective. Electron micrographs showed that the KRMV paticles are of spherical particles whereas the RPV particles are rod-shaped.

하순 및 하악골 정중열의 치험례

차두원,김현수,백상흠,김진수,변기정 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.3

Median cleft of the lower lip and/or mandible is a rare congenital anomaly, first mentioned by Couronne in 1819. Monroe(1966), Fujino(1970), Ranta(1984) and Oostrom(1996) conducted comprehensive reviews and list cases in literature. Median cleft varies greatly, from a simple vermilion notch to a complete cleft of the lip involving the tongue, the chin, the mandible, the supporting structures of the median of the neck, and the manubrium sterni. The associated anomalies include ankyloglossia, cleft tongue, neck contraction, heart lesion, absence of hyoid bone, and so on. The etiology of median cleft is unknown. Various possibilities, such as failure of mesodermal penetration into the midline, failure of fusion of mandibular processes, external factors apart from the embryogenic pattern such as prensure, position in utero, circulatory failure caused placental adhesion, diseases in pregnancy, and so on, have been discussed. A 8-year-old girl was referred to the Dept. of Oral & Maxillofacial Surgery, Kyungpook National University Hospital and had been aware of the fact that at birth "she had something wrong with her mouth." Shortly after birth she had been examined by a plastic surgeon and at that time surgical procedure had been performed to release the tongue from the lower jaw and lip at local hospital. On admission, she had a slight notching of lower lip and two fibrous frenum ran from the lip along the ventral surface of the tongue, diastema between her mandibular central incisors, and slightly constricted bifid mandible associated independent movement of the two halves of mandible. The patient had autogenous iliac bone graft to reconstruct the mandibular midline defect. The postoperative result was uneventful. In future, the correction of the soft tissue deformities such as notching of the lower lip and partial ankyloglossia will be required for the esthetic and functional improvement.

김진수,신상욱,박노부 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.4

The author studied on the 115 cases of the ameloblastoma which had been diagnosed with biopsy during the period of 1962 to 1994 at the Kyungpook National University Hospital, Pusan National University Hospital, Youngnam University Hospital, Keimyung University Hospital, Catholic Medical School Hospital, and Maryknol Hospital. This study contains the statistical analysis of the clinico-pathological findings such as sex, age, location, chief complaint, duration, treatment method, size, recurrence and impacted teeth in relation to radiographic findings. The results were as follows : 1. The incidence rate was 60% in .male and 40% in female. 2. At the time of diagnosis, the age of the patients ranged from 9 to 69 years old (average 31.4 years old). The cases of 73% were in the 2nd, 3rd and 4th decades of life. 3. The majority of cases, 88.7% occurred in the mandible, especially 59% in the mandibular angle area. 4. The most prevalent chief complaint of swelling was 56.5%. 5. As regards duration, the cases less than 12 months appeared 49.5%, and average duration is 30.45months. 6. Unilocular radiographic findings showed 43.5%, Multilocular radiographic findings appeared 56.5%. 7. Conservative treatment was performed 40.0%, and radical treatment was employed 60.0%. 8. There was the variation of lesional sizes between 2.0cm and 15cm, average size 6.19cm. 9. Recurrent cases were 28.7%, and impacted teeth were shown 30.43%. 10. The ratiographic finding has no relationship with the factors of age, location, chief complaint, recurrence and impacted teeth, however there is slight indication that the below 30-year-old patient tend to be related to the multilocular type. 11. The multilocular radiographic findings were shown more frequently in the groups of females, over average of 30.45 months, over average size of 6.19cm and radical treatment.

양측성 Warthin씨 종양 치험례

김상규,우길상,김진수,변기정 대한악안면성형재건외과학회 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.3

Warthin's tumor is a bunign neoplasm that occurs almost exclusively in the parotid gland. The tumor most frequently occurs in the tail of the parotid near the angle of the mandible. One unique feature of Warthin's tumor is the tendency of bilateral occurrence, which has been noted in 4 to 7 percent of cases. Most of these bilateral tumors do not occur simultaneously but are metachronous(occurring at different times). Histologically the tumor is composed of a mixture of ductal epithelium and a lymphoid stroma. Surgical removal is the treatment of choic for patients with Warthin's tumor. Warthin's tumor seldom recurs after removal. In our department, a 50-year old man, diagnosed as Warthin's tumor by fine needle aspiration biopsy, was treated by superficial parotidectomy on right side and subtotal parotidectomy on left side. For the treatment of Warthin's tumor, correct pretreatment diagnosis and the selection of appropriate surgical methods are important. We present a case report of the bilateral Warthin's tumor with the review of literatures.

The poor survival rates of patients with carcinoma of a tongue, despite of modern therapy, is well recognized. One of the most important prognostic factors is status of the cervical lymph nodes. There have been a long-standing debate about the treatment of cervical lymph nodes in early-stage tongue cancer. There are two major treatment opinion. The one is surgical excision of primary tumor with prophylactic neck dissection, simultaneously, and the other is to delay the cervical therapy until cervical lymph node is palpable. Recently we have experienced the early cervical metastasis in three patients who had been diagnosed as a carcinoma of the tongue. They were T1, T2 lesion and no palpable node was found. But histopathologic examination showed the occult metastasis or delayed cervical metastasis was occured. By the review of literature and clinical experience, we could conclude the prophylactic neck dissection offers a better chance for success than therapeutic neck dissection of palpable lymph nodes, in case of oral tongue cancer.

김성국,신홍인,박희경,장현중,김영미,김진수 大韓顎顔面成形再建外科學會 1996 Maxillofacial Plastic Reconstructive Surgery Vol.18 No.1

Ameloblastomas are benign epithelial neoplasm of the jaw comprising approximately 1-3.3% of all odontogenic cysts and tumors. Although most are microscopically benign, they are generally considered to be locally aggressive and destructive, exhibiting a high rate of recurrence. Treatments of them contain the conservative treatments on unilocular types and radical treatments on multilocular types. Classifications based on the histologic features of ameloblastoma generally included the follicular, plexiform, acanthomatous, basal cell, uncystic types. However, recantly a new and unusual variant has been added by Eversole et. al in 1984, the histologic features of which are characterized by marked stromal desmoplastic proliferation. This is a case report of desmoplastic ameloblastoma in the anterior maxilla of 63 year-old female treated by block excision. THis provides a brief review of the literature because of the rarity and unusual radiographic-histologic features of desmoplastic ameloblastoma.

하악골 Malunion에 따른 Transverse Mandibular Deficiency에 대하여 split and Replantation of Corticocancellous Bone Graft를 이용한 외과적 교정술의 증례보고

김진수 大韓顎顔面成形外科學會 1989 Maxillofacial Plastic Reconstructive Surgery Vol.11 No.1

Transverse mandibular deficiency is rare maxillomandibular malrelationship. Most of this malrelationship is considered to be caused by loss of bone substances. This can be corrected by subapical osteotomy, midsagittal vertical osteotomy, midline horizontal L sliding osteotomy, etc., case by case. In these cases, malrelationship after malunion of mandibular fracture, combination of vertical osteotomy and sliding autogenous cortical bone graft was used and favorable results were obtained. Advantages over previous traditional surgical methods were as follows : 1. This method provided easy access and good visibility. 2. It provided broad bone contact area, thus no other operation to obtain bone graft was needed. 3. There were little circumstances to extract teeth. 4. There were no difficulty in tongue movement after operation.

김태주,김진수 慶北大學校 齒科大學 1990 慶北齒大論文集 Vol.8 No.1

The purpose of this experimental study was to examine and compare the histological changes when anhydrous glycerol and normal saline applied to the sciatic nerves of rats perineurally in vivo. For this study, 30 Sprague-Dawley male ablino rats were used as the experimental animals and divided into 6 groups. The topical application of anhydrous glycerol on the right nerve of rats for 1 day, 3 day, 1 week, 2 week, 3 week and 4 week were used in experimental groups Ⅰ,Ⅱ,Ⅲ, Ⅳ,Ⅴ,Ⅵ. Physiological saline on the opposite site was the control in groups Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ. The animals were sacrified on the 1st and 3rd day, 1st, 2nd, 3rd, 4th weeks after experimentals and all specimens were fixed in 10% neutral formalin and 1% osmium tetroxide solution after, embedded in paraffin was and cross-sectioned with 4㎛. After these procedures, specimens were observed under the light microscope. The results obtained were as follows: 1. Our reselts show that myelin disintegration and axonolysis occur with glycerol application. 2. The degree of histological damage is proportional to the depth of penetration, and the fibers colsest to the perineurium showing maximal damage. 3. The maximal destruction of myelin were noted at one or two weeks. 4. There is no evidence of selective destruction of any groups of axons depending upon the degree of myelination, although myelin sheath shows the most striking histological change. J. Kyungpook Not.
